Crash under larger load and not able to boot into windows (lines down screen), Power issue?

[theaterix]

Afternoon all,

Its been a while!
Ive had an issue with my PC for a long while now, and its still there despite changing GPU's frm R9 290 to Vega 56...

To put the issue into a description, under any good load (going into a game etc) the pc freezes up and when I hold the power button to turn it off, and restart it it will show the spinning windows logo then instead of getting the login screen I get light blue lines down the screen.

Its bamboozling me and I have spent £300 on a GPU that didnt fix the issue, well it did, temporarily... So I suspect there is a power issue...

I have a CX750M with the spec in my signature, the PSU should be more than adequate for the system surely, unless it was starting to break...

light blue lines immediately ring alarm bells as that's a sign the gpu ram might have a problem, but it all depends on how old your psu is, it's tricky to pin point as a 750w psu should be enough for your build, if you have any other gpu's to test that will be the fist step, (gtx 1050 or similar), also go into your bios and see what the psu readouts are if they are below atx spec you may need a replacement.
also for testing set the cpu back to stock and set ram at xmp or back to jdec 2133mhz spec if needed and see what happens, have any gpu installed at this point.

I've just gone online to a psu calculator and made a rough guess with your specs of your pc and with the 290 installed you recommended psu wattage is 653w, when i change the gpu to a vega 56 your wattage recommendation is 608w both figures above take into account your cpu overclock but have the gpus at stock speed

Thank you for your reply,

I made a mistake and forgot about the overclocks being at 4.6, I had set everything back to stock, I will try the bios now and see what comes of it and get back to you...

So my PC no longer has a bios it appears, when I restarted it last night it did the lines again, and then it didnt work from any of the usual methods just leaving it for a while... Think its time for a new PSU... Turns out its been in service 3 and a half years now which I didnt realise!

As for the bios issue, in is place it is a blinking white line in the top left on a black background as if it is reading something to start?

what ever the case may bee your first step should defiantly be a new psu, its a big concerning that post screen no longer appears, did you try pressing f1,f2 and del keys at start up, if you did that and didn't get into the bios screen that's not a good sign, but firstly a good quality gold or platinum psu should be considered as at the end of the day the psu is responsible for the whole pc and a poor chose will case damage if not careful.
just before you install the new unit download hardware info 64 and run sensors, with in is all your info about the pc scroll down a bit until you see your mobo name, within this tab you should see readouts for your psu which should look like this

+5v
+12v
3vcc

that will show what the readouts are of your psu and it will show the max, min and average which is very helpful, if anything is wrong the program will flag any value as red, but if the values are just above atx spec i would still look at a new psu in any case, if the psu is over 3 years old shes had a good run indeed

"quote" As for the bios issue, in is place it is a blinking white line in the top left on a black background as if it is reading something to start?

if you see the little white line blinking at the top that means the pc has past the post screen and is looking for the boot drive so windows can start, if your able to restart do so but start pressing either f1, f2 or del and you should get into the bios, you may have set it up to not display at post and have a wait time of a couple of seconds which is why you dont see it, default on all boards is full screen logo and a 5 second window before it will boot into windows, but those options are full customisable in the bios to your liking

Here is a screenshot of the power outputs on the motherboard: https://gyazo.com/beebff1a304881a5cbba41a953a43d6a

Here is a screenshot of my 1tb Samsung HDD that has a warning on it.... That is my drive i put movies etc onto: https://gyazo.com/9d69637a510a30acbeb59578759fc482

Might try disconnecting that drive and seeing if it makes any difference.

Seems all power readings are in line? Unless them being slightly higher would be an issue???
